#copy(opts = {}) ⇒ `Object`

This operation copies a disk to the specified storage domain.

For example, copy of a disk can be facilitated using the following request:

POST /ovirt-engine/api/disks/123/copy

With a request body like this:

<action>
  <storage_domain id="456"/>
  <disk>
    <name>mydisk</name>
  </disk>
</action>

If the disk profile or the quota used currently by the disk aren’t defined for the new storage domain, then they can be explicitly specified. If they aren’t then the first available disk profile and the default quota are used.

For example, to explicitly use disk profile 987 and quota 753 send a request body like this:

<action>
  <storage_domain id="456"/>
  <disk_profile id="987"/>
  <quota id="753"/>
</action>

Parameters:

opts (Hash) (defaults to: {}) —

Additional options.

Options Hash (opts):

:async (Boolean) —

Indicates if the copy should be performed asynchronously.
:disk (Disk)
:disk_profile (DiskProfile) —

Disk profile for the disk in the new storage domain.

Disk profiles are defined for storage domains, so the old disk profile will not exist in the new storage domain. If this parameter is not used, the first disk profile from the new storage domain to which the user has permissions will be assigned to the disk.
:filter (Boolean) —

Indicates if the results should be filtered according to the permissions of the user.
:quota (Quota) —

Quota for the disk in the new storage domain.

This optional parameter can be used to specify new quota for the disk, because the current quota may not be defined for the new storage domain. If this parameter is not used and the old quota is not defined for the new storage domain, the default (unlimited) quota will be assigned to the disk.
:storage_domain (StorageDomain) —
The storage domain where the new disk will be created. Can be specified using the id or name attributes. For example, to copy a disk to the storage domain named mydata send a request like this:
```
POST /ovirt-engine/api/storagedomains/123/disks/789
```
With a request body like this:
```
<action>
  <storage_domain>
    <name>mydata</name>
  </storage_domain>
</action>
```
:headers (Hash) — default: {} —

Additional HTTP headers.
:query (Hash) — default: {} —

Additional URL query parameters.
:timeout (Integer) — default: nil —

The timeout for this request, in seconds. If no value is explicitly given then the timeout set globally for the connection will be used.
:wait (Boolean) — default: true —

If true wait for the response.

def get(opts = {})
  internal_get(GET, opts)
end

#move(opts = {}) ⇒ `Object`

Moves a disk to another storage domain.

For example, to move the disk with identifier 123 to a storage domain with identifier 456 send the following request:

POST /ovirt-engine/api/disks/123/move

With the following request body:

<action>
  <storage_domain id="456"/>
</action>

For example, to explicitly use disk profile 987 and quota 753 send a request body like this:

<action>
  <storage_domain id="456"/>
  <disk_profile id="987"/>
  <quota id="753"/>
</action>

Parameters:

opts (Hash) (defaults to: {}) —

Additional options.

Options Hash (opts):

:async (Boolean) —

Indicates if the move should be performed asynchronously.
:disk_profile (DiskProfile) —

Disk profile for the disk in the new storage domain.

Disk profiles are defined for storage domains, so the old disk profile will not exist in the new storage domain. If this parameter is not used, the first disk profile from the new storage domain to which the user has permissions will be assigned to the disk.
:filter (Boolean) —

Indicates if the results should be filtered according to the permissions of the user.
:quota (Quota) —

Quota for the disk in the new storage domain.

This optional parameter can be used to specify new quota for the disk, because the current quota may not be defined for the new storage domain. If this parameter is not used and the old quota is not defined for the new storage domain, the default (unlimited) quota will be assigned to the disk.

end

#refresh_lun(opts = {}) ⇒ `Object`

Refreshes a direct LUN disk with up-to-date information from the storage.

Refreshing a direct LUN disk is useful when:

The LUN was added using the API without the host parameter, and therefore does not contain any information from the storage (see DisksService::add).
New information about the LUN is available on the storage and you want to update the LUN with it.

To refresh direct LUN disk 123 using host 456, send the following request:

POST /ovirt-engine/api/disks/123/refreshlun

With the following request body:

<action>
  <host id='456'/>
</action>

Parameters:

opts (Hash) (defaults to: {}) —

Additional options.

Options Hash (opts):

:host (Host) —

The host that will be used to refresh the direct LUN disk.
:headers (Hash) — default: {} —

Additional HTTP headers.
:query (Hash) — default: {} —

Additional URL query parameters.
:timeout (Integer) — default: nil —

The timeout for this request, in seconds. If no value is explicitly given then the timeout set globally for the connection will be used.
:wait (Boolean) — default: true —

If true wait for the response.

Options Hash (opts):

:async (Boolean) —

Indicates if the remove should be performed asynchronously.
:headers (Hash) — default: {} —

Additional HTTP headers.
:query (Hash) — default: {} —

#service(path) ⇒ `Service`

Locates the service corresponding to the given path.

Parameters:

path (String) —

The path of the service.

Returns:

(Service) —

A reference to the service.

Raises:

(Error)

# File 'lib/ovirtsdk4/services.rb', line 33599

def service(path)
  if path.nil? || path == ''
    return self
  end
  if path == 'permissions'
    return permissions_service
  end
  if path.start_with?('permissions/')
    return permissions_service.service(path[12..-1])
  end
  if path == 'statistics'
    return statistics_service
  end
  if path.start_with?('statistics/')
    return statistics_service.service(path[11..-1])
  end
  raise Error.new("The path \"#{path}\" doesn't correspond to any service")
end

#sparsify(opts = {}) ⇒ `Object`

Sparsify the disk.

Sparsification frees space in the disk image that is not used by its filesystem. As a result, the image will occupy less space on the storage.

Currently sparsification works only on disks without snapshots. Disks having derived disks are also not allowed.

Parameters:

opts (Hash) (defaults to: {}) —

Additional options.

Options Hash (opts):

:headers (Hash) — default: {} —

Additional HTTP headers.
:query (Hash) — default: {} —

Additional URL query parameters.
:timeout (Integer) — default: nil —

The timeout for this request, in seconds. If no value is explicitly given then the timeout set globally for the connection will be used.
:wait (Boolean) — default: true —

If true wait for the response.

#statistics_service ⇒ `StatisticsService`

Locates the statistics service.

Returns:

(StatisticsService) —

A reference to statistics service.

end

#update(disk, opts = {}) ⇒ `Disk`

This operation updates the disk with the appropriate parameters. The only field that can be updated is qcow_version.

For example, update disk can be facilitated using the following request:

PUT /ovirt-engine/api/disks/123

With a request body like this:

<disk>
  <qcow_version>qcow2_v3</qcow_version>
</disk>

Since the backend operation is asynchronous the disk element which will be returned to the user might not be synced with the changed properties.

Parameters:

disk (Disk) —

The update to apply to the disk.
opts (Hash) (defaults to: {}) —

Additional options.

Options Hash (opts):

:headers (Hash) — default: {} —

Additional HTTP headers.
:query (Hash) — default: {} —

Additional URL query parameters.
:timeout (Integer) — default: nil —

The timeout for this request, in seconds. If no value is explicitly given then the timeout set globally for the connection will be used.
:wait (Boolean) — default: true —

If true wait for the response.

Returns:

(Disk)
